ROTARY EXPLOSIVE-ENGINE.

Specification of Letters Patent.

Patented July. 25, 1911.

Application filed December 6,1910. Serial N 0. 595,975.

To all whom it may concern:

'Be it known that 1, Cinemas M. JORDAN,

a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Rotary Explosive-Engines, of which the following is a specification.

My invention relates to improvements in the arrangement of the compression chamber within the head of the engine and its relation to the rotary piston, also the manner of placing the charge of vapor within the explosive chamber. 1 attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1. is a vertical section of the machine from. side to side. Fig. 2. is a vertical section from front to back. Fig. 3. is a View of the back of the head.

Similar letters of reference indicate corresponding parts throughout the several views.

A. is the case inclosing the entire moving parts of the machine.

B. is the head of the case, with an extension passing into the cylindrical portion of the rotary piston the extension being circular in section and concentric with the circumference of the case at its inner face and acting as a bearing for the rotary piston (1.

C. is the rotary piston, composed of a cylinder closed at its back end, having a central hub for the insertion of a shaft and having a projection G on its periphery, which is the piston proper.

'D. is an abutment between the inlet and outlet ports of the case A.

C is the piston proper, which is not cast upon the cylindrical part, but is fastened to it by the inclined side pieces C, which raises the abutment D. at the proper time and also prevents its too sudden return, the spring E. always pushing it to seat.

Through the extension of the head B. is a cylindrical hole F. parallel to the face of the head, which is the con'ipression chamber and within it is the piston G. which is made to move back and. forth in unison with the revolution of the engine piston C by suitable mechanism to be hereinafter described.

At the top of the compression chamber is a plate H. which closes it at this end, with the exception of a slot 1. which is the port of exit for the'compressed gas or vapor, from the compression chamber F. to the space J. behind the piston -C before explosion.

This vapor is only allowed to pass when the slot, or port, K. in the piston cylinder C.

is opposite the slot I. through the plate H.

The extension of the head B. also contains a water acket chamber 2., which surrounds the compression cylinder F for the purpose of keeping the cylinder cool.

L. is the spark plug entering the explosion chamber J. and properly connected with a source of electricity and timing mechanism.

M. is the exhaust port of the engine.

Referring to Fig. 2. is the inlet port to the compression chamber F. being directly connected to a check valve G. from without. The rotary piston cylinder 0. is closed at its inner end and has a central hub for inserting the shaft P. on its outer side; this hub passes into another hub on the case A. which acts as a bearing for it. B is a pin, which is partly embedded in the compression piston (i. and the remainder in the plate S. The plate .S.'slides in a wide dovetailed groove '1. at the back of the extension of the head 13 and has a wide slot U. which I is engaged by the roller V. on the crank pin W., said crank pin being screwed into the pin 11. to move up and down freely.

llaving now described the different parts of the machine, I will now explain its mode of action. ward the right, in so doing the roller V. on the crank-pin \V., being engaged in the slot- U. of the plate 8., carries this plate down; the COII'IPIOSSlOll piston G. being attached to this plate by the pin 1%. is also carried down with it and in so doing draws explosive vapor througlr' the check-valve O. and inlet port N. to the compression cylinder 1 when the compression cylinderis The piston cylinder C. turns tofull of vapor the check-valve O. closes and on the return stroke of the compression piston G. the gas is compressed and cannot escape, until the port K. in the piston cylinder C. is opposite the [port I. in the top plate H., the va or then escapes, under pressure, into the explosive chamber J the port K. passes and closes the exit of the vapor through the port 1.; at this instant the vapor is ready to be exploded by a spark from the spark plug L. The spark plug is connected with a source of electricity and a timing mechanism, and, as the abutment D. is rigid, the force of the explosion comes upon the piston (l forcing it around until the wedge shaped pie'ces C strike the bottom edge of the abutment D. and pushes it up, ,.allowing the piston projection C to pass. In the meantime the compression piston G. has drawn in another charge of vapor and compressed it, which passes into the explosion chamber when the port K. is opposite the port I. In this way there is a compression and explosion of vapor at each revolution of the piston of the engine. The explosion chamber is kept tight by packing rings marked fl. on the drawing Fig. 2. The exhaust port M. is alwaysopen and the gases from the previous explosion are pushed out by the piston C as it revolves.
